Abstract: A water-resistant cartridge includes a pyrotechnic that when ignited launches water from a disrupter cannon to disable and/or destroy an explosive device. The cartridge includes a seal that seals between an outer surface of the cartridge and an inner surface of the barrel to limit water that escapes from the barrel rearward of the seal and cartridge.

The force provided by the pyrotechnic blows a cover of the cartridge off to provide the force directly to the water to launch the water.
